Methods and systems for specifying and enforcing network policies are provided. One method for configuring a network that includes a plurality of heterogeneous network access devices includes creating a network enforcement profile based on at least one enforcement policy, and determining a network access device group of the plurality of heterogeneous network access devices that are capable of managing the enforcement profile. The method further includes providing vendor-specific configuration parameters for at least one network access device of the network access device group so as to cause the network to manage the network enforcement profile, and applying the vendor-specific configuration parameters to the at least one network access device.
